Personally, I found BDSM to be the perfect place to process my own sexual trauma and reach some kind of equilibrium in my relationship with my sexuality in my early 20s. My therapist raised an eyebrow when I told her about it, years after the fact, but that's because she's an old-fashioned hetero-monogamous lady. To me, the power that comes with Topping has healing properties. I don't know if it works with other people, but I would love to hear about research into BDSM as a treatment for sexual trauma victims.
